overloading std::string operators requires template<> syntax ! Howto ?

[lalebarde]

Hi all,

I need to overload a cast to u_int32_t of std::string. I wrote this :

string::operator u_int32_t() const {return 0;}

But the compiler says :

error: specializing member ‘std::basic_string<char>::operator u_int32_t’ requires ‘template<>’ syntax

I used to using templates for a while, but here, I really don't know how to manage it. Any idea please ?

Conversion operators has to be class members. You can't add members outside the class definition so it's not possible to do what you are trying to do.
